I'm Using an API example that transform a string into a dictionary and then calculate its md5. Unfortunately there is just a python example and I never developer in this language. So far I tried my best and I'll append what I did. Python code:
What I tried so far is:
But I got some errors because some of the things are quite difficult for me to convert into vb.net For example, how can I use params_XXX without declaring them? Why is it using the word Json while basically I need to pass a String to it?
I got roughly 25 errors and most of them are in the Public Function add_sign_to_params . It is really difficult for me to convert these functions into vb.net as they might have different construction in python.
I am not asking for a ready code, I'm asking help to convert it step by step.
For example, I've already searched on google how to convert a string to md5, but this code is not just converti a string to md5, it is using kind of weird and complex ( to me ) structures like "sort_keys = True, indent = 4)"..
Thanks
Code:
import hashlib
import json
def params_string_to_dict(params_str):
params = params_str.split("&")
params_dict = {}
for param in params:
key, value = param.split("=")
params_dict[key] = value
return params_dict
def params_dict_to_string(params_dict):
params_str = ""
items = params_dict.items()
for key, value in items:
params_str += key + '=' + value + '&'
return params_str[:-1]
def add_sign_to_params(params_dict, api, secret):
params_dict['api_key'] = api
params_str = json.dumps(params_dict, sort_keys=True, indent=4)
params_str = params_dict_to_string(json.loads(params_str))
params_str += '&secret_key=' + secret
hash_md5 = hashlib.md5(params_str.encode(encoding='utf-8'))
sign = hash_md5.hexdigest().upper()
params_dict['sign'] = sign
return params_dict
params_url="Api url"
params_str = "Api endpoint".replace(" ", "")
params_dict = params_string_to_dict(params_str)
#print(params_dict)

params_str = params_dict_to_string(params_dict)
print( params_url +"?" + params_str)Code:
